T all whom it may concern: i

Beit known that I, GEORGE H. Mo'rr, a citizen of the United States, residing` at West Union, in the county of Fayette andState of Iowa, have invented a new and useful Watering-Trough, of which the following is a specication.

The invention relates to improvements in watering-troughs.

One object of the present invention is to improve the construction of watering-troughs and to provide asimple, inexpensive, and eficient device capable of automatically controlling the flow of water into the drinking-l receptacle and of shutting off the flow of the same when the water risesto the desired height and of starting the flow 'of the water when the contents of the drinking-receptacle are consumed to a sufficient extent.

A further object of the invention is to arrange the valve mechanism so that access to the same may be readilyhad for repair or other purposes.

The invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claim hereto appended.

In the drawings, Figure 1 is a perspective view of a watering-trough constructed in accordance with this invention. Fig. 2 is a vertical longitudinalsectional view. Fig. 3 is a transverse sectional view. Fig. 4 is a detail sectional view illustrating the construction of the joint for connecting the short pipes with the chamber or casing.

Like numerals of reference designate corresponding parts in all the figures of the drawings.

1 designates a drinking-receptacle composed of two portions or lobes to form a double drinking-trough, and it is connected with a chamber or casing 3 by short upper and lower pipes 4 and 5, the lower one forming a passage for water and the upper one servingas a vent and permitting any overflow from the casing to be discharged into the drinking-receptacle. The upper and lower short tubes or pipes have threaded terminals, and their front ends are provided with nuts 4' and 5", their rear ends being screwed into suitable threaded openings of the chamber or casing 3, and

washers 4b and 5b are arranged on the eXte-x rior-of the drinking-receptacle at points opposite the nuts 4a and 5f. The threaded openings of the chamber or casing 3 are reduced at their inner ends to form shoulders 6 and 7, and the adjacent ends of the pipes or tubes 4 and 5 are beveled to fit the shoulders, whereby a tight joint is effected to prevent any leakage.

The rear end of the casing, which is rectangular, isA provided with a removable plate 8, fitted in a recess of the rear end of the chamber or casing and secured to the same by screws 9 or other suitable fastening devices, a washer 8 of rubber or leather being interposed between the removable plate 8 and the inner wall of the recess to providea water tightjoint. The outer face of the removable plate is flush with the adjacent outer face of the casing, and the said plate .is provided with a. tubular extension forming a valvecasing. The tubular extension 10, which is provided on its interior with a valve-seat 11, receives a valve 12, preferably constructed of elastic material and connected by a stem 13 with one arm of a bell-crank lever 14, which extends into the casing 3 and carries a fioat 15, provided with a removable cap 15'nl and adapted to be operated by water rising within the casing 3. The lever 14, which consists of a long arm and a short arm, is fulcrumed at its angle on the removable plate, which is provided at its inner face with projecting perforated ears 16 to receive thek pivot of the lever. The float 15 is constructed of any suitable sheet metal or analogous material which will not rust. The flexible valve 12, which is mounted on the stem 13, is held in place by means of a Washer 17 and a nut 18, which engages the threaded outer or rear end of the stem. The tubular arm or valve-casing is exteriorly threaded at 19 and receives a tubular or cylindrical cap 20, having a perforated outer end 2l, forming a strainer.

The device is designed to be connected with any suitable source of supply, which may consist of a reservoir, tank, barrel, or the like, and as the water owing through the valvecasing rises within the drinking-receptacle and the lioat-casing 3 the fioat will be raised until the valve closes on the seat, when the supply will be' shut off. As soon as the wa- IOO ter is consumed to a sufficient extent to permit the ioat to descend the valve will be moved backward by the oat and opened to start the Water again. By this construction the valve is purely automatic,bein g controlled in opening and closing by the movement of the iioat.

The invention has the following advantages: The Watering-trough is simple and comparativelyinexpensive in construction, it is strong and durable and adapted to be applied to a barrel, tank, or other suitable source of supply, and it is purely automatic in its operation. The parts may be readily assembled and separated and ready access to the valve mechanism is aorded.

Changes in the form, proportion, size, and the minordetails of construction within the scope of the appended claim may be resorted to Without departing from the spirit or sacricing any of the advantages of this invention.

A device of the class described, comprising a drinking-receptacle having two lobes to form a double drinking-trough, a chamber'or casing, upper and lower short lengths of pipes connecting the central portion of the rear of the said receptacle to the front end of the casing, a plate detachably secured to the rear end of the said chamber or casing and having an outwardly-extending horizontally-disposed tubular arm arranged at the center thereof and having a rear valve-seat, a cap removably mounted on the arm over the valveseat and having a strainer-covering at its rear end, a Valve movably mounted in the seat and having a stem projecting through theV
